Patent GB-478769-A (GB)
Title: Improvements in or connected with rangefinders and like optical measuring instruments
IPC: G01C3/14
Filed: 1937-01-14
Abstract: 478,769. Range - finders. BARR & STROUD, Ltd., and FRENCH, J. W. Jan. 14, 1937, No. 1111. [Class 97 (i)] Relates to stereoscopic range-finders, in which the images of the observed object are compared with a reference mark formed by stereoscopic fusion of two mark images. In such instruments, measurement is sometimes effected by a pair of prisms in the beam forming one image, these prisms being rotatable about a common axis in opposite directions so as to produce an additive effect in the plane of measurement without producing any vertical movement of the image. In order to avoid the disadvantage due to surface losses in only one of the beams in such an arrangement, a range-finder according to the invention is provided with a single prism in each of two image-forming beams, the prism being rotatable about the axis of the beam to measure the range, and the arrangement being such that, while each image is caused to move vertically in its field, the vertical movements are the same. Fig. 2 shows an ortho-stereoscopic instrument having internal reference marks of which images a, b, Fig. 3, are seen in the field of view, c, d being the images of the observed object. Prisms P, P<1> are provided in the two limbs of the instrument and are connected together so as to turn simultaneously about the optical axis through the same angle in the same direction. This rotation causes movements of the images c, d in the measuring plane and also vertical movements to the positions c<1>, d<1>, the line c<1>d<1> being parallel to cd. Fig. 4 shows a pseudo-stereoscopic instrument in which a single prism P<2> can be used to act on both beams F, F<1>, being placed in the parts f, f<1> of the beams which are side-by-side. Fig. 6 shows an instrument having a pseudo-stereoscopic system F, F<1> as in Fig. 4, and an orthostereoscopic system H, H<1> forming additional images of the observed object to serve as reference marks. A single prism P<4> is placed in the parallel portions f<1>, h of the right-hand pseudo-stereoscopic beam F<1> and the lefthand ortho-stereoscopic beam H, both of which form images in the left-hand eyepiece E. Rotation of the prims causes these images a, c, Fig. 7, to be displaced vertically to the positions a<1>, c<1>, the displacements being the same so that the line a<1>b remains parallel to the line c<1>d. Specification 325,956, [Class 97 (i)], is referred to.

Abstract: 1,110,993. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. 9 Jan., 1967, No. 1201/67. Heading H1K. In a method of making semi-conductor devices in multiple an impurity is diffused into a predetermined region or regions of a wafer of the opposite conductivity type and grooves etched in at least one face of the wafer so as to form isolated regions of said opposite conductivity type. The wafer is then subdivided into devices each containing at least one of these regions. In the embodiment PNPN switches are made by evaporating aluminium on to both faces of a 175� N type silicon wafer, etching to the form of two opposed grids, and diffusing it in to form a P type grid extending through the wafer. The entire surface of the wafer is next converted to P type by diffusing gallium through an oxide coating. Phosphorus is then deposited on and diffused into one face through apertures etched in the oxide coating to form N regions. Both faces are covered with oxide masking 12 (Fig. 8) and nickel electrodes 11 electroless plated on the exposed areas. After dipping in molten solder which adheres to the plating, a photo-resist mask is applied to leave only the grid region exposed. The overlying oxide and the wafer is then etched in this region down to the N type wafer material (Fig. 11). After applying a protective layer of silicone rubber the solder contacts are re-exposed by abrasion and the wafer divided along the grooves into individual elements. In an alternative method aluminium is diffused into only one face and the grooves formed in the other. To form a bi-directional switch additional N type regions are formed on the lower face of the wafer and beneath the site of the gate contact.
